HELP with collection

I have a collection on my credit report that is for $201.28 to Progress Energy.

The problem I am having with it is that the new collection agency that bought it is reporting it as a new collection in 07/2012. I know this is from 2006 when my Husband lost his job and so I called Progress Energy to confirm, and they told me it was sent to collections in July of 2006.

I have tried to do online disputes, but they have all been unsuccessful. What can I do next?

We are getting ready to apply for a mortgage and I know that a collection as recent as 07/2012 is not going to be ok. What can I do?
